Comparison of Sensitivity and Low Frequency Noise Contributions in GMR and TMR Spin Valve Sensors with a Vortex State Free Layer
Herbert Weitensfelder, Hubert Brueckl, Armin Satz +9
Magnetoresistive spin valve sensors based on the giant- (GMR) and tunnelling- (TMR) magnetoresisitve effect with a flux-closed vortex state free layer design are compared by means…

Considering non-uniform current distributions in magnetoresistive sensor designs and their implications for the resistance transfer function
Anton Bachleitner-Hofmann, Claas Abert, Hubert Brückl +5
Non-uniform current distributions of spin valves with disk shaped free layers are investigated. In the context of spin valves, the vortex state, which is the ground-state in many d…
